350z and Exhaust laws

8 posts in this topic

Posted · Report post

I would love to give my 350z an aftermarket exhaust and loved the sound of the invidia Gemini and berk hfc's. But I believe that in wa the maximum db is 90 and there is no way this setup or an aftermarket exhaust would be under these limits right? Don't feel like getting an citation and having to remove it!!

I doubt you’d be under the limits with the hfc’s    

Maybe with just the catback. If it’s any help I have an Amuse catback and it’s not that loud. I wouldn’t be worried if I were to be tested.

I run the Invidia Gemini with stock cats and a popcharger, and there's no way it's under 90db. If you want it quieter than 90db you'll probably need some extra mufflers or a light right foot

Thanks Rob. So have you been pulled over for the exhaust at all or no real problem so far? Can't decide whether to to just get it and use a light foot Sent from my SM-G920F using Tapatalk

I'm in country Vic and I don't do a lot of driving so I haven't been hassled over the exhaust, it's quite easy to keep it sounding respectable if you are light on the throttle. It's when the car is under load or at high revs that it starts to get louder.

    • 370z Wheel choice – Australian market research - FYI

      Good choice of wheels, now let’s see some pics. I’ve just ordered a set of Nismo wheels from america .
    • 370z Wheel choice – Australian market research - FYI
      By paracin · Posted
      After 2 months of market and forums research, I bought my new wheels – 19” Kiwamis. The following factors were considered: wheel size and spacers, quality, price and the supplier’s customer service. To determine the right size, I thoroughly studied 17 pages of “370z wheel fitment guide” on The370z forum and settled for 9.5 +25 and 10.5 +12, which should provide a flush fit without spacers or camber adjustment while accommodating larger tyres (if so inclined after suspension upgrade). Quality-wise, after considering some questionable 20” Taiwanese options like XXR ($1200+), Koya ($2400+), Vertini ($2800+ with 35% off), Rohana and Ferrada (both over $3K), I settled for a proper JDM option – Work Emotion Kiwami AHG (matte bronze), deep concave front and ultra deep concave rear. JDM Concept’s price is not only cheaper than the above, but also cheaper than Work USA. Regarding customer service, my first choice of wheels were Gram Lights or Weds but I didn’t get a quote from Aaron in nearly 4 weeks (he did apologise); Koya (Koya wheels), Venero (representing Ferrada wheels) and B.Boss (for Vossen VFS-1) NEVER even acknowledged receipt of my web inquiry; the main players on Princess highway between Tempe and Arncliffe, where I inquired in person, were totally disinterested, one even outright rude. (Is it my grey hair, I wonder, that causes people not to take me seriously in a Zed?) The shining stars of customer service are: Leonardy from JDM Concept, representing Work wheels, who replied to all my emails within an hour, often quicker. He specialises in Work wheels and is extremely helpful and accommodating (eg I picked up my wheels within 3 hours from committing to the purchase). George from Rollenso employed significant efforts to assist me with finding the right Lenso wheels. George is experienced, knowledgeable and helpful. I also ordered the tyres from George cheaper than Tempe, and that’s saying something.
    • Offset for Wheels to clear Brembos
      By Punked · Posted
      I think you are both a little confused. Lower offsets wheels (wheels closer to outside or poke from guard) will generally give you more brake clearance. However, some high offset wheels (wheels more sunken from outside of guard) will clear too. Hugely depends on the wheel/spoke shape and design. The factory wheels are 18x8+30 (or close?) and clear Brembo brakes but many aftermarket wheels in those specs will not clear. I run 19x10+15 and 19x11+15 on my 350Z and they clear by a mile. The same wheel as mine in a 18x8+20 probably wouldn't clear... You really need to try some wheels on your car....you will find many of the Japanese wheels are made to clear larger brakes (not always though)... https://www.1010tires.com/Tools/Wheel-Offset-Calculator# this is the best for fitment- won't help with your clearance issue though. Cheeeeeers

      If I remember correctly there was a recall here in Aus as well but only for certain series of that part number. I would demand to talk to the dealer principal rather than some service monkey that knows nothing but how to extract cash from loyal customers and demand the part be replaced (possibly costing labour which is fair) for a known faulty part that was subject to a nationwide recall. Search this forum for more info on the recall. Sent from my iPad using Tapatalk

      By peter a · Posted
      Ummmm !! Experienced the 'No start' and the orange key light.  2012 model 370Z. Tried the hammer trick, tried it again and again and again and eventually it released. Leave the accessory light on and removed the fuse. Car starts OK now. Quote from Nissan for a new ESCL(electronic Steering Control Lock) is $1,580.13 plus GST plus labour.
